ANGLE-LATH-CUTTNG- MACHINE.

Application led September 14, 1922.

i' '0 @ZZ fic/mm. t may concer/n.

Be it known that l, FnANoisoUs JosnrHUs Bininnmniws, a subject 'of the Queen of Holland, residintg` at Eindhoven, the Netherlands7 have invented certain new and useful improvements in Angle-Lath-Cutting` Machines, ot which the following is a specification.

lily present invention has 'for its object an el'licient machine for the cheap production of angle lathe such as are used, inter alia7 ior packinp` purposes.

My novel jii'iachine comprises two crossed arbors, each carrying a nest of circular saws the circiunt'erences oi"A which lie on a conin cal surface. Said shafts are adjustable in such a manner that mating saws in both nests have a` common tangent in the direction oit movement oit the work piece. It a board is passed along nests of circular saws disposed as described it will be cut int-o angles desired.

ln view ot the desirability tov cut the angles from planed lumber, the sawing ina chino is preferably combined with a planing machine to form a self contained unit therewith. The lumber is then fed automatically towards the saws and the angles may7 it' so desired, be discharged automatically.

l am aware that trimming or initering machines have been noposed with crossing saw arbore. but these machines generally recuire a special. cutter to complete the operation. l ani also aware that dovetailing .i chinos have beni suggested with nests of circular saws the circinniferences oi which ne on a conical surface, but in these machines the saws cooperate in another manner than in my novel machine and, moreover, the purpose oi? said known devices is not the production of angle lathe.

Serial No. 588,250.

rThe annexed drawing illustrates, by wav ot example only, a machine in accordance` with my invention, Figure l being a side elevational view and Figure 2 a front elevational view thereof. Figure 3 shows a cross sectional view ot a board cut into angle laths.

From the dra-wing it follows that the crossed 'saw arbors l and 2 each carry a nest of circular saws 3 and 4t respectively, the circumferences of the saws in each nest lying on a conical surface. The bearing l, lb and 2, 2b respectively of the arbore l, 2 are adjustable by means of slides le, ld and 2C, 2 respectively, in such a manner, that each saw arbor may he displaced in parallel relation with itselt. Thev saw arbore may consequently be adjusted so that corresponding saws in both nests of saws have a common tangent in the direction of motion of the board a. supported on the vertically adjustable table 5. The cuts produced by the saws divide the board (t in a plurality of angle laths c1, c2, c3.

The ieed rollers 6, 7, the cutter head 8 and the pressure block 9 torni parts of the planer with which my novel sawing machine has been combined to 'form a selfcontained unit.

in a machine for cutting angle laths, two crossed saw arbors each carrying' a nest of circular saws the circumi''erences ot' which lie on a. conical surface, said arbore being adjustable in such a manner that correspending` saws in both nests have a common tangent in the direction of :teed of the workpiece.

ln testimony whereof aix my signature.
